The earth being mu ... by the earth's surface. The earth being much cooler than the sun, remits radiation most strongly at infrared wavelengths. Water vapor, carbon dioxide and ozone then absorb much of this radiation and r ...

I will determine how the lengt ... gth and width of the jelly affect how the radiation is attenuated. The loss of the intensity of the infraredradiation is represented by the amount of voltage across the infrared detector. If the inte ... cross the infrared detector. If the intensity of the radiation is high, then the voltage across the infrared detector will also be high.Apparatus (before pilot experiments)Infrared transmitter and det ...

reenhouse gases trap heat, and thus warm the earth because they prevent a significant proportion of infraredradiation from escaping to space. Concentration of greenhouse gases, especially CO2, have i ...
